6 Claims. 1

This invention relates to certain new and useful improvements in window sash construction.

It has for one of its objects to provide a combination sash and storm window construction which is simple, compact and inexpensive in construction, and which is so mounted in the frame as to swing horizontally relatively thereto to a position for ventilating or to facilitate washing the window sash or storm window from the inside of the building.

Another object of the invention is to provide simple and effective means for detachably mounting and clamping the storm sash on the window sash.

Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended'claims.

In the accompanying drawings:

Figure 1 is an inside perspective view of my window construction showing the same in a partially open position. Figure 2 is an outside perspective view showing the same in a partially open position. Figure 3 is an enlarged fragmentary cross section taken on line 33, Figure 1.

Figure 4 is a fragmentary horizontal section taken on line 4- l,Figure 3. Figure 5 is a detached perspective view of the fitting for detachably clamping the storm window to the sash.

Figure 6 is a transverse section taken on line .3:

6-6, Figure 5, showing the parts in clamping position. Figure 7 is a perspective view of the sash-lashing fitting.

Similar characters of reference indicate corresponding parts throughout the several views.

In the preferred embodiment of my invention shown in the drawings, l0 indicates the window frame of ordinary construction, which is supported in the building walls in the usual man- .ner, and H indicates the outside sill and I2 the inside sill. The main sash l3 of the window is of the easement type hinged to swing horizontally and outwardly on upper and lower hinges whose fixed leaves I4 are secured to the inside face of the window frame. The companion movable hinge leaves l5, which are of angular or L-shape in cross section, each include an outer flange or portion l6 connected at its outer end to the companion hinge-pintle and adapted to lie flatwise against the adjoining side of the window frame in the closed position of the sash, and an inner flange or portion I l at substantially right angles to said outer flange and connected to the adjoining outer face of the sash l3, as shown in Figure 4. The joint faces of the sash I the sash and the sill H for regulating the opening and closing of the swinging sash from the inside and for retaining it in predetermined open positions for ventilating purposes. In Figure 4 is shown, by dotted lines, a screen frame 23 which may be removably applied to the frame inwardly of the sash during the summer months, and which does not interfere with the opening and closing of the sash.

Detachably fitted to the outside of the main sash l3 to provide an air or insulating space therewith and to swing jointly therewith on the hinges l5, I6 is a storm sash 24 of substantially the same shape and area as such main sash and which fits firmly and snugly in its closed position against the face of the outer sill I2 and the adjoining side and top inner faces of the window frame If]. Furthermore, as shown in Fig-- ure 6, the edges of both the main and storm sash are preferably grooved, as indicated at 25, to intercept and shed any rain which might find its way between the joint edges of the sash and the frame. The flange portion N3 of each hinge leaf I5 has a pin or dowel 2B. projecting therefrom with its axis substantially parallel to that of the companion sash-connected flange portion ll of said hinge leaf and the opposing edge of the storm sash 24 has ferrule-fitted openings 21 therein for receiving such companion hingebearing pins 26 to support the hinged side of the storm sash thereon. The opposite or free side edge of the storm sash, substantially centrally between its top and bottom edges, is provided with a means for effectually detachably clamping it to the outside of the main sash as well as urging it into firm coupling engagement with aoeaooi 3 in register with such slot in which a verticallyswinging latching plate 35 operates. This latching plate is pivoted at 32 to the inner bracketfiange and terminates at its free or outer end in a laterally-bent operating lug or handle 33, which, in its latched or operative position, shown in the drawings, registers with the bracket-slot 29 and is flush with the joint edge of the sash so as not to interfere with its closing. At its oppositeor pivoted end the latching plate has a tongue 34 projecting therefrom for latching engagement with an opening 35 formed in the transverse lug 38 of a companion angle-shaped bracket 31 secured to and projecting from theopposing outer side of the sash 53, said lug being free to pass, during the closing and opening movements of the storm sash; into and out of a registering opening 38 formed in the opposing flange of the bracket 28 and in the operating plane of the latching plate tongue 34. The latter has'a cam face or raised portion 39 thereon which, in the latching position of the parts, bears against the opposing edge of the lug-opening 35 in the companion main sash bracket 3'! to thereby firmly draw the storm sash toward the main sash as the latching plate is swung to its operative position. Simultaneously with this action, those inner edges of the latch plate above and below its tongue 34 abut against the opposing face of the bracket-lug 35 while the opposite face of-the latter abuts against the oppositeedge of the bracket-opening 38.

vWhen it is desired to remove the storm sash 24 fromthe main sash t3, the combination window is unlatched by raising the lever is to rea.

lease it from the companion catch 25 and then opened to the position shown in Figures 1 and 2 through the medium of the hand crank assembly 22, it being noted that both sash swing as'a unit-on the hinges I; IS. The latching plate Si is now swung upwardlyto-withdraw its tongue 34 from the opening in the lug 35 of the main sash bracket 31, after which the free end of the storm sash is fulcrumed outwardly to free I said tongue 3d from the sash bracket-opening 38; The storm sash is then pulled away from the hinges to uncouple the same fromthe hingepins 26. The mounting of the storm sash on the main sash is accomplished by a reversal of procedure just described; It-shOuld also bementi oned that in the open position of the'w-indow, the window-panes can be conveniently washed on their outside from within the house, there being sufficient space at its hinged end to allow the arm to extend therethrough to wash the adjoiningportion of the window.
